Digital literacy is increasingly recognised as a critical skill for healthcare professionals to enhance patient care and public health outcomes. A mixed-methods approach including pre- and post-course surveys and focus group discussions was employed to gather data from a sample of 120 healthcare professionals. Findings indicated that participants' self-reported digital literacy improved by 35% after the courses, with significant improvements in EHR use (p < 0.05) and telemedicine delivery skills. The study highlights the potential of digital literacy training to enhance healthcare professionals' practice skills in Northern Nigeria. Further research should be conducted to evaluate long-term outcomes and explore broader impacts on patient care quality. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
